Preventing Mold Growth in HVAC Systems

If you have central air in your home, then you know just how wonderful of a piece of equipment it can really be. However, if the proper care isn't taken, the HVAC unit in your home can actually become one of the most dangerous items around. The reason for this is that HVAC units are pretty susceptible to mold growth. Luckily, preventing mold growth in HVAC systems is more a matter knowing what steps to take. You don't need any special training, but rather all you need to do is follow these simple guidelines.

  • Periodic cleaning. Just as with most things, by periodically and regularly cleaning your HVAC system, you can dramatically decrease the chance of any mold growing. Take the time to periodically clean around the vents, and take a careful look at any dust that you may find. If the dust looks darker than it should, or even black, then you may have mold to deal with.
  • Check for condensation. Often HVAC units are kept near water heaters, and other sources of moisture. Prevent mold growth in your HVAC system by periodically checking to ensure that there is no condensation inside any of the ducts, or near any vent covers. If there is, find the source of the moisture and eliminate it. Mold really loves to grow in dark, moist areas, and what could really be more dark or moist than the ducts of your HVAC system?
  • Check any fittings and seals. As you conduct your cleaning, and are checking for any condensation, make sure that you also check the fittings and seals of your HVAC unit as well. Periodically checking to ensure that the seals and fittings on your HVAC system are tight will help ensure that no mold growth gets into your system, as well as helping to ensure that excessive moisture doesn't get in as well.
  • Regular maintenance. Follow a maintenance schedule for your HVAC unit. This means that you should check, change, and replace any filters as needed. In addition, it doesn't hurt to have a professional come and perform routine maintenance on your HVAC system once a year at a minimum. This will cover the vast majority of the potential problems that you may have, as well as provide a professional's opinion on whether your system needs any special care.
  • Don't be afraid to call a professional. If you find any black mold, or if you are simply worried that you may have it, do not be afraid to call a professional. While a professional duct cleaner will cost more, they certainly have the expertise and equipment needed to remove any growth that may have been found because it's too late.
